As for agriculture, its true that it too will increase in the future, but not in the way assumed by the reading passage. The truth is, in the United States, less and less land is being used for agriculture every year. Increases in agricultural production have resulted from and will continue to result from the introduction of new, more productive varieties of crops. These new crops produce more food per unit of land, and as a result, theres no need to destroy wilderness areas.
对于农业来说,确实需求会越来越大,但是农业的增长并不是以阅读所提及的方式实现的。在美国,实际上用在农业领域的土地每年都在减少。农产品产量的增加是因为引进了新的、产量更高的农作物品种,而这种趋势将会持续。这些新的农作物有更高的亩产量,因而,就没有必要破坏原有荒地用作农耕了。
And third, while its certainly true that traditional pesticides have been destructive to birds, its incorrect to project this history into the future. Now that, people are aware of the possible consequences of traditional pesticides, two changes have occurred. First, new and much less toxic pesticides have been developed, and thats important. Second, and perhaps more importantly, there is a growing trend to develop more pest resistant crops, crops that are genetically designed to be unattractive to pests. Pest resistant crops greatly reduce the need for chemical pesticides, and best of all, pest resistant crops dont harm birds at all.
